Col. Esteban Arias says 28-year-old Tabitha Leah Ritchie was stopped while trying to board an Air Canada flight in Bogota after an inspector noted that her belly was unusually cold and hard. He says police discovered a false belly made of latex taped to her body and they found 2 kilograms (4.4 pounds) of cocaine.

Police say Ritchie arrived in Colombia on Aug. 6 and he identified her as a social worker.

The Canadian Embassy did not respond to requests for details.

Officials say 874 foreigners are held in Colombian lockups, most on drug charges.
